Chavez is accused of running a red light in north Houston about 7:45 p.m. Saturday and colliding with a Chevrolet Suburban with seven people, including four children, ages 8, 4, 3, and 4 months.

Prosecutor Alison Baimbridge filed two counts of intoxication assault because of injuries suffered by the 4-year-old boy and the 3-year-old girl. The third-degree felony carries a punishment ranging from two to 10 years in prison.

Baimbridge said during the brief court appearance that Chavez failed several field sobriety tests and had a blood alcohol concentration of 0.17, more than twice the state's legal limit for operating a motor vehicle, which is .08. She said Chavez appears to be a resident of Mexico.
